Customs officers in the port of Gdansk have discovered 33 kilos of pure cocaine in a shipment of second hand engines.

The drugs were hidden in a container on board a freighter arriving from Uruguay on the order of a Polish company. Police traced the consignment to an international drugs ring. Four persons, Poles and Germans, have been arrested so far in connection with the case.

The market value of the intercepted cocaine is estimated at 10 million zloty, roughly 2.3 million euro - the biggest discovered attempt at drug smuggling in Poland this year.

Thanks to joint actions of Customs Service officers and agents of the Central Bureau of Investigation (CBS) a total of 44 kilograms of cocaine has been seized at various border checkpoints since the beginning of 2009.  (ss/pg)
